Abstract
The utility model relates to a non-negative pressure pump station with a water hammer protection function. The non-negative pressure pump station with the water hammer protection function comprises a water regulation air chamber jar, a water supply regulation harmonic jar and a plurality of frequency conversion water pumps. A water inlet end of the water regulation air chamber jar is connected with tap water pipelines. The water outlet end of the regulation air chamber jar is connected with the water inlet end of the frequency converting water pumps. When the pump suddenly stops, the water hammer is caused, high pressure water inside the water supply regulation harmonic jar quickly makes up for stabilizing water pressure behind the pump.
